如何根据List <string>字段数对List <List <string >>进行排序？

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class ListSort {
    public static void main(String[] args) {
        List<List<String>> list = new ArrayList<>();
        list.add(Arrays.asList("a", "b", "c"));
        list.add(Arrays.asList("d", "e", "f"));
        list.add(Arrays.asList("g", "h", "i"));

        Collections.sort(list, new Comparator<List<String>>() {
            @Override
            public int compare(List<String> o1, List<String> o2) {
                return o1.get(1).compareTo(o2.get(1)); // 根据第二个字段进行排序
            }
        });

        System.out.println(list);
    }
}
